made according tovand embodying the pri`nmy present invention; and Fig. 2 is Similar charactersof reference are einployed in the above described 'cate corresponding parts. f

bustion en ine is operated by means of an explosive fuel which does not require the.

use of atmospheric air to support its comfor example, as a fuel formed from two parts of hydro en gas and one as described in my previous application for Letters-Patent` of the United States, led April 112th, 1917, Serial Number 161,555, and I will therefore describe the novel construction of the present he novelA construction. of internal com views, to indi'- invention when' used with such a fuel as illustrative of its use and operation, although I do'not wish to be understood as limiting in any way the construction or use of my novel engine in connection with such ere are other combinations Vof aseswhich may be capable of use as the fuel or operating my said novel engine.

Referring now tothe said drawings, 1 is the engine cylinder, which is preferably provided with the water-jacket 2, and has at vthe top a combustion chamber 3; 4 is the piston, the connectin rod 5. This connecting rod is attached to t e crank 6, which is carried by the shaft?. Entering the combustion chamber 2 is the spark-plug 8 supplied by any well known s stem of electrical ignition. All of this is ofythe'ordinary 'combustion engines. y

Connected with the enginecylinder .1 is a suitable housingA 9 in which is rotatably mounted arevolving admission valve, coinprisingV a valve drum 10 providin a valve chamber 11 communicating .wit which, through the wall .of said drum, is a valveport 12. Said housing 9 outer end with an inlet-port 13, and at its inner end with an outletort 14 which comustion chamber 3. Connected with'said valve drum 10 is a shaft 15, which projects exteriorly ofsaid housing 9, and upon which is arranged a sprocket 16 driven by the chain 17 ,from a sprocket 18 mounted on the engine shaft 7, so that said rotary admission valve mechis provided at itsl anism is properly timed in its operations relative to the movement of the piston 4. Connected `With the side of said cylinder 1 is an exhaust valve, comprising an exhaust port 19 formed in the walls or said cylinder and properly positioned, relatlve to the p iston movement, so as to communicate with the combustion chamber 3. Connected with said cylinder andregistered with said exhaust port 19 is a valve housing 2K0 1n which is arranged a spring closed exhaust valve 21 normally .closing said exhaust port 19.

The reference character 22 indicates a tank adapted to contain a supply of hydrogen gas stored under pressure, preferably of about four thousand pounds to the square inch. Connected with the outlet of this hydrogen supply tank is a reducing valve 23, which permits the flow of hydrogen gas from said tank at a reduced pressure of preferably about one hundred and titty pounds to the square inch.

The reference character 24 indicatesa tank adapted to contain a supply of oxygen gas stored under pressure, preferably of about'four thousand pounds to the square inch. Connected with the. outlet of this oxygen supply tank isla reducing valve 25,A which permits the flow of oxygen gas from said tank at a reduced pressure of, preferably, about one hundred and fifty pounds to .the square inch.

The reference character 26 indicates a measuring valve casing, preferably, provided with a Water jacket 27. Rotatably mounted in said valvecasing isa revolving measuring valve,l comprisin a valve-drum 28, the interior of which is ivided into two separate measuring chambers, to wit,'a hydrogen measuring chamber 29 and an oxygen measuring chamber 30. rlhe volume of the hydrogen measuring chamber 29 is twice that of the-oxygen measuring chamber 30.

Said valve casing 26 is provided with a hydrogeninlet port. 31 connected byv suitable piping or conduits 32 Awith the reducing valve of the hydrogen supply tank; and said valve casing is further provided with an oxygen inlet port 33 connected by suitable piping or conduits 34 with the reducing valve of the oxygen supply tank. In like manner said valve casing 1s provided with' a hydrogen outlet port 35, and an oxygen outlet port 36. Said revolving valve is provided in its circumferential walls with a hydrogen valve port 3 7 communicating with said hydrogen measuring chamber 29, and

Vsuccessively registering with the respective hydrogen inlet port and outlet port of the valve casing, as said valve drum is rotated; and, said revolving valve isv further provided in its circumferential Walls with an oxygen valve port 38 communicating with said oxygen measuring chamber 30, and suc'- cessively registering with the respective preferably nemesi arranged a sprocket 40 driven -by a chain 41 from a sprocket 42 mounted on the engine shaft 7, so that the rotary measuring valve mechanism is properly timed in its operation relative to the engine operation.

43 indicates a mixing retort or chamber, the casing 44 of which is provided with a hydrogen inlet 45 connected with said hydrogen port 35v of said measuring valve casing by suitable piping or conduit connections 46, and further provided with an oxygen inlet 47 connected vyith said oxygen outlet port 36 of said measuring -va-lve casing by suitable piping or conduit connections 48. The casing 44 of said mixing retort or chamber 43 is also provided With a gas or fuel outlet'49, which communicates aol through suitable piping or conduit 50 with the inlet port 13 o the housing 9 or said revolving admission valve connected with the engine cylinder 1.

The Water from the engine cylinder Water-jacket 2 is preferably discharged through piping 51 connected with the latter. Connected in the line of said piping 51 is a circulation pump 52, driven by a sprocket 53 and chain 54 from a sprocket 55 mounted on the engine shaft 7. Said piping'l is connected with said Water jacket 27 of said measuring valve casing 26 into which it dischargesl and vthe Water jacket 27 of said measuring valve casing 26 discharges through return piping 56 back to the engine cylinder Water-Jacket 2, with which the discharge end of said return piping 56 is connected.

rIhe novel construction of internal combustion engine, as thus above described, when driven by an explosive fuel mixture comprised of hydrogen and oxygen, operates as follows i A supply of hydrogen gas is stored or con- Y valves 23 and 25 are-set to liberate the' ases .from their respective tanks at a re uced pressure of about one hundred vand fifty pounds. The ases thus liberated are conducted to the inlet ports of the measuring valve. Said measuring valve drum 28 being driven directly from the engine shaft, ro-

tates in properly timed relation to the piston 'movement of the engine, consequently the same operates to measure the fuel, elements 1n proper time and quantity to provide a constant supply of fuel gas for delivery to the engine cyhnder according to the needs lof the engine. Upon rotation, the valve drum 28 alines the valve ports 37. and 38 with the res ective ports 31 and 33, whereupon the hydrogen` gas flows into the hydro- 'gen measuring chamber 29, and the oxygen as Hows into the oxygen measuring chamger 30. When using the elements -hydrogen gas and oxygen gas in combined or intermixed form to provide the explosive fuel, it is necessary to use two parts o hydrogen gas to one part of oxygen gas, consequently the measuring chambers 29 and 30 are respectively sized to measure the separate gases 1n such res ective proportions. Since, then, the chamber 29 is twice the size of the chamber 30, the measured volume of hydrogen gas will always be twice that of the measured volume of oxygen gas, while the pressure of the separate volumes Ais maintained in e uality. The measuring valve being loaded, its continued rotation carries theV valve orts 37 and 38 into' alinement with the outet ports 35 and 36, thereby releasing the respective measured volumes of hydrogen andoxygen gases into the mixing retort or chamber 43, wherein the separate gases are p ermitted to comingle or intermix to provlde the resultant explosive fuel. The outlet .49

of the mixing retort or chamber 43 is connected by means of the conduit V50 with the rotary gas admission valve mechanism connected with ythe engine. The valve drum 10` being driven directly from the engine shaft, rotates in proper] timed relation to the piston movement o lthe engine, consequently the same operates to receive and then liberate into the engine cylinder, in timedintervals relative to the piston operation of the engine,.measured quantities of the fuel mixture, therein to be ignited to produce the force for driving the engine. When the valve port 12 of thevalve drum 10 registers with the gas inlet 13 of the housing 9, the fuel mixture passestherethrough and intothe drum 10. The continued rotation of the drum 10 resents its valve port 12 in registration -with the gas outlet 14, communicating with the engine cylinder Vcombustion chamber, thereupon releasing .the fuel mixture so that the same flows'into said combustion chamber ready to ignited. As the piston passes slightly the top of its stroke .the fuelmixture is ignited with explosive force which is directly applied to the piston to produce the power stroke of the latter.

- The combustion of the fuel mixture, comprised of hydrogen and oxygen, results in the conversi'onofD the mixture into water and steam', which is exhausted from the cylinder when the exhaust port 19 is uncovered by the downwardl moving piston through the exhaust valve dsevices 20 and 21.

Since the drawing off of the component gases hydrogen and oxygen from the stored sources at reduced pressure greatly lowers hot-water.

1 the outlet of said mixing from-the engine watergacket 2 through the conduit 51, is introduce through the water-jacket 27 back to the engine water-jacket 2 through the conduit 56. A (p A p 52 driven from the engine shaft, an placed in the line of said conduit 51 serves to continue such circulation of the about the measuring valve gives ofi` its heat units, so that the same ma be absorbed by the fuel as elements contained in' the measuring va ve, and thus raises the temperature ofnsaid gases, at the same time lowering the temperature of the water, which may then be returned to the engine water-jacket 2 to prevent over-heating of the engine cylinder.

Of course it will be understood that my invention is adapted for application to mul` tiple cylinder enGines, der engines, and same may as well as single c linthat the 'principles o the be lreadily applied to both two cycle and four cycle engines.
